This SAE Aerospace Information Report (AIR) examines the need for and the application of a power train usage metric that can be used to more accurately determine the TBO for helicopter transmissions. It provides a formula for the translation of the recorded torque history into mechanical usage. It provides examples of this process and recommends a way forward. This document of the SAE HM-1 IVHM Committee is not intended as a legal document and does not provide detailed implementation steps, but does address general implementation concerns and potential benefits.

This SAE Aerospace Standard (AS) specifies standardized gland design criteria and dimensions for static face seals for internal pressure and external pressure applications for aerospace hydraulic and pneumatic applications using the same size range as AS4716 and AS5857 where applicable. Some small diameter sizes are excluded because they are not practical. The glands have been specifically designed for applications using AS568 size elastomeric O-rings with related Class 2 tolerances at nominal system operating pressures up to 3000 psi (20 680 kPa) utilizing no anti-extrusion (backup) rings. While the gland dimensions herein have been designed for pressures up to 3000 psi (20 680 kPa) these glands may be used for higher pressures, but extra precautions need to be taken and testing should be performed to ensure to ensure integrity of performance. This specification covers the basic design criteria and recommendations for use with standard size elastomeric O-rings, however, these glands are also suitable for use with other elastomeric and polytetrafluoroethylene (PTFE) based seal geometries.

This SAE Recommended Practice establishes uniform procedures for testing battery electric vehicles (BEV’s) which are capable of being operated on public and private roads. The procedure applies only to vehicles using batteries as their sole source of power. It is the intent of this document to provide standard tests which will allow for the determination of energy consumption and range for light-duty vehicles (LDVs) based on the Federal Emission Test Procedure (FTP) using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS), and provide a flexible testing methodology that is capable of accommodating additional test cycles as needed. Realistic alternatives should be allowed for new technology. Evaluations are based on the total vehicle system's performance and not on subsystems apart from the vehicle. NOTE: The range and energy consumption values specified in this document are the raw, test-derived values. Additional corrections are typically applied to these quantities when used for regulatory purposes (Corporate Average Fuel Economy, vehicle labeling, etc.).

A hydraulic purifier is used in remediation of contaminated fluids by removing air, particulate and water to clean the fluid to within the requirements of the system where the fluid is being used. This standard provides requirements for standard tests to evaluate purifier performance so that users can determine the best purifier for their use.

The vacuum brake hose is intended for use in the power braking systems of vehicles or as connections on transmission lines in combinations of vehicles or systems thereof. For the purposes of clearly identifying hose classification and for specification simplification, vacuum brake hose is divided into two types: heavy-wall Type H, and light-wall Type L.

This SAE Standard covers hose fabricated from fabric braid and synthetic rubber, assembled with end fittings for use in automotive power steering applications at pressures as indicated in Table 1B, as flexible connections within the temperature range of -40 ×C (-40 ×F) to 121×C (250 ×F) average, 135 ×C (275 ×F) maximum peaks. These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsations is not required.

This SAE Standard gives methods for testing and evaluating performance of the SAE 100R series of hydraulic hose and hose assemblies (hose and attached end fittings) used in hydraulic fluid power systems. Specific tests and performance criteria for evaluating hose assemblies used in hydraulic service are in accordance with the requirements for hose in the respective specifications of SAE J517. This document further establishes a uniform means of testing and evaluating performance of hydraulic hose assemblies.

This SAE Recommended Practice is intended for use in testing and evaluating the performance of Light Duty automotive electric engine cooling fans. These Electric Cooling Fan (ECF) Assemblies are purchased by Light Duty Truck and Passenger Car OEM’s from suppliers. They are purchased as complete assemblies, consisting of the fan(s), motor(s), and shroud (see Figure 1); this Recommended Practice will only consider such complete assemblies. Some purchased assemblies using brush-type motors may also include control devices such as power resistors or pulse width modulation (PWM) electronics for speed control. In the case of brushless motor technology, the controller is an integral part of the motor where it also performs the commutation process electronically. The performance measurement would include fan output in terms of airflow and pressure, and fan input electric power in terms of voltage and current. This information could then be used to calculate the efficiency of the assembly, including aerodynamic efficiency of the fan and shroud and electrical efficiency of the motor.

It also provides the means for documenting and checking the declared (rated) power published by the manufacturer.
